13th Luso-Brazilian Transplantation Congress, 12th Portuguese Transplantation Congress and 1st Iberian Meeting of TransplantationIschemia-reperfusion injuryComparison Between IGL-1 and HTK Preservation Solutions in Deceased Donor Liver Transplantation

The effectiveness of liver preservation solutions remains in evidence. Cold ischemia time, steatosis, expanded criterion donors, operational cost, and survival represent important roles in its success. In a prospective cohort study between August 2009 and April 2014, 178 patients were allocated into an Institut Georges Lopez - 1 (IGL-1) solution group (63.5%) or histidine-tryptophan-ketoglutarate (HTK) group (36.5%). There were no differences among recipient's characteristics including age, skin color, gender, Model for End-stage Liver Disease score, acute rejection, cholestasis, and reperfusion syndrome incidences. Also, donors, age average, skin color, donor risk index, time in intensive care unit, hemodynamic variables, infections, and steatosis incidences were similar. The average cold ischemia time was 494 minutes in the IGL-1 group and 489 minutes in the HTK group (P = .77). Alanine aminotransferase and aspartate aminotransferase serum levels on the first postoperative day were 707 and 1185 mg/dL, respectively, with IGL-1 and 1298 and 2291 mg/dL, respectively, with HTK (P = .016) and similar at day 15 (P > .88). The incidence of delayed graft function was 4.5% with IGL-1 and 4.6% with HTK (P = .90). The incidence primary nonfunction was 2.7% with IGL-1 and 3.1% with HTK (P = .71). The incidence of perioperative death was 11.5% with IGL-1 and 13.8% with HTK (P = .94). The survival in 30 months was 86% in IGL-1 group and 82% in HTK group (P = .66). Both preservation solutions are efficient to liver transplantations with deceased donors. Major prospective trials are necessary to evaluate each preservation solution's particularities. The preservation solution availability in each transplantation center must guide its use at the present moment.
